@billbennett $8 per day is fine, it's the whole, I tried to do that and got no roaming service and was still charged.
Of course, later on I found out that the U.S. is opposed to certain Chinese branded phones, which mine is, and that might be why I couldn't get any service through the U.S. company proxying the service. I ended up leaving my phone on airplane mode for the whole two weeks and using wifi when possible.
